It has b integrally. Lock slide switch 10
When is slid in the unlocking direction Y _RELE , the lock engaging portion 10b is separated from the lock engaged portion 6b.

Next, the operation of the conventional card mounting device will be described.

In the unmounted state in which the IC card m is not inserted, as shown in FIG. 7, the protrusion-like locked portion 6b of the card take-out lever 6 is usually a hook-like lock of the lock slide switch 10. It is in a locked state in which it is locked by the locking portion 10b, and the card mounting slide plate 2 is retracted to the rear end portion thereof by the urging force of the return spring 4. When the IC card m is inserted from a card insertion opening (not shown) and placed on the card placing slide plate 2 as shown in FIG. , The pin terminals of the IC card m are electrically and mechanically connected to a connector (not shown) of the information processing device (electronic notebook). At this time, I
The back end of the C card m is received by the card stopper 2a.

The electronic notebook is operated with the IC card m inserted, and the input or calculated data is registered in the IC card m. While the IC card m is in use, the locked state is maintained as shown in FIGS. That is, the card eject lever 6 to which the biasing force of the return spring 4 is applied via the lever receiver 2b of the card mounting slide plate 2 is pushed to the back side (X _IN direction), and the card eject lever 6 for locking is locked. The locking portion 6b is locked by the locking locking portion 10b of the lock slide switch 10, and the card ejection lever 6 is in a locked state. In this case, even if the operation portion 6a of the card take-out lever 6 is pushed in the take-out direction X _OUT , the card take-out lever 6 does not move, so that the IC card m is also kept in the inserted state and is not accidentally taken out. .

When removing the IC card m, the following operation is performed. As shown in FIG. 8, first, the operating portion 10a of the lock slide switch 10 is pushed in the unlocking direction Y _RELE . As a result, the locked state of the lock locking portion 10b with respect to the lock locked portion 6b is released. That is, the locked state of the card ejection lever 6 is released. In this unlocked state, if the operating portion 6a of the card take-out lever 6 is pushed in the take-out direction X _OUT against the urging force of the return spring 4, the locked portion 6b for locking is locked from the locking portion 10b for locking. Because it is off,
Move the card eject lever 6 around the support shaft 8 (X
It can be swung in the _OUT direction).

Card take-out lever 6 take-out direction X
Along with the swing to _OUT , the oval convex portion 6c in the middle of the card ejecting lever 6 pushes the lever receiver 2b of the card mounting slide plate 2 in the same direction X _OUT, and the entire card mounting slide plate 2 is pushed. With IC card m, take out direction X
Move it to _OUT . Thus, the IC card m is removed from the card insertion slot (not shown).

[0011]

The conventional card mounting device has the following problems.

That is, as shown in FIG. 9, immediately after the IC card m is taken out, before the card take-out lever 6 is returned to the original position by the urging force of the return spring 4, some kind of operation mistake causes a lock. It is assumed that the slide switch 10 is pushed in the lock direction Y _LOCK . Then, the hook-shaped locking engaging portion 10b of the lock slide switch 10 becomes the protruding locking engaged portion 6
As it goes into the return swing locus of b, the protruding lock-engaged portion 6b or the portion of the card ejecting lever 6 near the lock-engaged portion 6b is locked as shown in the drawing. Then, the card take-out lever 6 cannot further return and swing, and cannot return to the normal origin position. Further, the card mounting slide plate 2 cannot be returned to the normal origin position.

When the IC card m is inserted while the card take-out lever 6 is stuck, when the IC card m is forcibly inserted, the leading end of the IC card m is a card stopper of the card mounting slide plate 2. There is a risk of being deformed or damaged by receiving a large reaction force from 2a.

When the operation portion 6a is strongly pressed to force the card ejection lever 6 to return to the original position, the locked portion 6b of the card ejection lever 6 and the locking portion of the lock slide switch 10 are locked. There was a risk that a large stress would be applied between 10b and 10b and the parts would be damaged.

The present invention was devised in view of such circumstances, and even if the lock slide switch unexpectedly returns to the locked state due to an operation error before the card take-out lever returns to the home position. Then, even if the card is inserted or the card ejecting lever is returned to the original position in that state, it is an object to prevent the card from being deformed, damaged, or damaged.

[0016]
